I have a Wholesaling Question

[Evan Young]

The situation is the seller is willing to sell me their property for $350K. I have a qualified cash buyer for $375 that is willing to buy the property at that price. I could go into contract and assign to end buyer but since I have the pieces in place, I'd rather have end buyer go to contract directly with seller and merely state my fee in the contract. Is that a frequent practice or a possibility to do? I am also  broker but this is all off market. Replies are welcomed. Thank you!
